Just wanted to point out that there's an outstanding bug report due to some changes in Boost.Container that seem to have occured somewhere in the 1.52 dev cycle, reported here <https://svn.boost.org/trac/boost/ticket/7650>. In a nutshell, there is a compile time error caused by boost::container::list::const_iterator is trying to use a method called 'to_pointer' that doesn't exist (there is a 'pointer_to' method defined). We're using a modified version of boost/container/list.hpp at the moment, but it would be nice to ditch that come 1.53. The patch is so trivial that I thought it best to leave it up to the maintainer, as I really have no idea how to work with the current svn setup. cheers, Rich
